Title: High energy photon-neutrino interactions

Abstract

A general decomposition of the amplitudes for the 2{r_arrow}2 processes {gamma}{nu}{r_arrow}{gamma}{nu} and {gamma}{gamma}{r_arrow}{nu}{bar {nu}} is obtained using gauge invariance and Bose symmetry. The restrictions implied by this decomposition are investigated for the reaction {gamma}{gamma}{r_arrow}{nu}{bar {nu}} by computing the one-loop helicity amplitudes in the standard model. In the center of mass, where {radical} (s) =2{omega}, the cross section grows roughly as {omega}{sup 6} up to the threshold for W-boson production, {radical} (s) =2m{sub W}. Astrophysical implications of very high energy photon-neutrino interactions are discussed. {copyright} {ital 1998} {ital The American Physical Society}

  • We present a systematic study of low-energy neutrino--two-photon interactions to lowest order of {ital O}({alpha}{sub em}{ital G{ital F}}). General structures of such interactions are analyzed. Differences due to whether neutrinos are Dirac particles or Majorana particles are discussed. Simple formulas are derived from which one can easily obtain the corresponding effective neutrino--two-photon interaction in all theoretical models. The compatibility of a small neutrino mass with a large neutrino--two-photon interaction is explored. Some physical implications of such interactions are also examined.
  • From 12 000 charged-current ..nu../sub ..mu../D events obtained in an exposure of the Fermilab 15-ft bubble chamber to a high-energy wide-band neutrino beam, the absolute neutrino flux is determined using the reaction ..nu../sub ..mu../n..--> mu../sup -/p. For the total charged-current cross section, sigma/sub t/ = kE/sub ..nu../, k = (0.68 +- 0.04 +- 0.10) x 10/sup -38/ cm/sup 2//GeV is obtained for E/sub ..nu../ between 10 and 200 GeV. No clear energy dependence of the slope parameter k is observed.

  • The propagation of UHECR nuclei for A = 1(protons) to A = 56(iron) from cosmological sources through extragalactic space is discussed in the first lecture. This is followed in the second and third lectures by a consideration of the generation and propagation of secondary particles produced via the UHECR loss interactions. In the second lecture we focus on the generation of the diffuse cosmogenic UHE-neutrino flux. In the third lecture we investigate the arriving flux of UHE-photon flux at Earth. In the final lecture the results of the previous lectures are put together in order to provide new insights intomore » UHECR sources. The first of these providing a means with which to investigate the local population of UHECR sources through the measurement of the UHECR spectrum and their photon fraction at Earth. The second of these providing contraints on the UHECR source radiation fields through the possible observation at Earth of UHECR nuclei.« less
